What is the main purpose of using companion planting in ornamental gardening?

The main purpose of using companion planting in ornamental gardening is to enhance growth and deter pests naturally. Companion planting is based on the principle that certain plants can benefit from being grown together. For instance, some plants can attract beneficial insects that prey on pests, while others may improve nutrient availability in the soil, leading to healthier and more vigorous growth.

Furthermore, specific combinations can help reduce competition for resources, improve pollination, and create a balanced ecosystem within the garden. This approach minimizes the need for chemical pesticides and fertilizers, promoting a more sustainable and environmentally friendly gardening practice. Overall, the interplay between companion plants can lead to healthier ornamental gardens and more robust plant growth.

While other choices mention important aspects of gardening, such as aesthetics, blooming speed, and shading, they do not capture the primary benefits associated with companion planting, which focuses specifically on natural growth enhancement and pest deterrence.
